At a glance

The offset advances less than its own depth: a 10" offset moves only 5-3/4" along the run. That is its only real advantage, and the reason it gets used in very tight spots.

The depth has to beat the shoe radius

Two bends of angle θ on a shoe with centerline radius R need about 2R(1 − cos θ) of depth before their arcs stop overlapping. Cos 60° is one half, so at this angle the formula simplifies to R itself: the offset must be at least as deep as the shoe's radius.

Estimate for these three shoes; other models differ.

The arithmetic hides this. A 2" offset at 60° gives marks 2-3/8" apart, which looks bendable on paper. In the shoe, the second bend would start inside the first. Under about 1-11/16" of depth the marks themselves are less than 2" apart and practically on top of each other.

Sticker values (1.2 and 1/2"/in) to the nearest 1/16". * Marks closer than 2". Faded rows are too shallow for any of the three shoes above.

Each depth is above that shoe's minimum. Distances are from the cut end to the point where the offset must be complete.

Notice how far the second mark lands past the finish point: the shrink is half the depth, so on the 1" job the second mark sits 5" beyond it. Forgetting the shrink on a 60° offset is a short pipe every time.

Sticker 1.2 and 1/2" vs exact

Both trade numbers are off, in different ways. The multiplier 1.2 is larger than the true 1.1547, so the marks land too far apart and the offset bends 3.9% too deep: 1/2" on 12", 15/16" on 24". The shrink rule of 1/2" per inch is under tan 30° = 0.5774, so the pipe also ends up shorter than the rule says: 15/16" at 12" of depth, 1-7/8" at 24".

For a deep 60° offset that has to land in a fitting, use 1.155 and 0.577 or the offset calculator in exact mode.

When to bend something else

Because each 60° offset is 120°, a run with one of them has only 240° left for everything else. Pulling tension builds with every degree of bend, so a steep offset near the far end of a long pull is felt at the tugger. Options worth weighing first:

• A 45° offset if you can find 1-5/8" more pipe between bends (at 8" deep). It saves 30° and is easier to sight.
• A single kick when the pipe does not need to come back parallel, for example heading into a box or up a wall at an angle. One bend instead of two; see the kick calculator.
• Two 90s for very deep changes of level. They add 180°, more than a 60° offset, but the marks come straight off the take-up, the result is square, and the depth is set by measured straight pipe instead of an angle you sight by eye. The back-to-back 90 calculator lays them out.

A degree either way

An 8" offset laid out with 1.2 puts the marks 9-5/8" apart. What comes out:

The sticker overshoot is bigger than a degree's worth of bending error here, so a 60° offset bent a degree or two shy of the mark lands closer to the planned depth than a perfect one.
